Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

It should be noted that, in this disclosure, the terms "first," "second," and the like in the description and the claims, and in the drawings, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Since the response speed of the engine is slower than that of the motor, as shown in fig. 1, when a command to charge the high-voltage battery is received, the response time period t1 of the motor in response to the command to charge is shorter than the response time period t2 of the engine in response to the command to charge. In the response time t2 of the engine, the rotating speed of the engine is continuously increased, and in the process of increasing the rotating speed of the engine, if the driving torque of the whole vehicle is unchanged, the output torque of the engine is distributed to the motor to be used for generating insufficient torque (insufficient motor charging torque), and the negative torque of the motor to the engine can cause abnormal flameout of the engine.

In view of the above, the present disclosure provides a method, medium, device and vehicle for controlling engine output torque of a hybrid vehicle, so as to solve the problems in the related art, and improve the stability of vehicle running when the vehicle starts charging a high-voltage battery while reducing the risk that the engine is prone to flameout when the hybrid vehicle starts charging the high-voltage battery.

FIG. 2 is a flowchart illustrating a method of controlling engine output torque of a hybrid vehicle, according to an exemplary embodiment. Taking the whole vehicle controller as an execution main body as an example, the steps of the engine output torque control method of the hybrid vehicle are executed. Referring to fig. 2, the method includes the following steps.

In step S11, in response to an instruction to charge the high-voltage battery of the hybrid vehicle, a required charging torque that satisfies the high-voltage battery charging demand and a required generating torque that satisfies a target load operation of the hybrid vehicle are calculated to obtain a vehicle-to-vehicle generating torque of the engine.

The whole vehicle power generation torque is the sum of the required charging torque and the required power generation torque.

In step S12, a minimum required generation torque that satisfies a first target load operation related to vehicle running and safety among the target loads is calculated.

In step S13, the power generation output torque of the engine is controlled to increase to the vehicle power generation torque in accordance with the required charging torque, the required power generation torque, and the minimum required power generation torque.

In specific implementation, the vehicle controller can directly acquire the charge state of the high-voltage battery, and can also acquire the charge state of the high-voltage battery through a battery management system and the like, so as to determine whether the high-voltage battery needs to be charged according to the charge state of the high-voltage battery. For example, in the case where the state of charge of the high-voltage battery is lower than a preset state of charge threshold, an instruction to charge the high-voltage battery of the hybrid vehicle is generated. And determining the required charging torque of the engine for meeting the charging requirement of the high-voltage battery when the high-voltage battery is charged according to the charge state of the high-voltage battery.

It may be noted that the required charging torque provided by the engine to the generator for satisfying the charging requirement of the high-voltage battery is related to the universal characteristic of the engine and the conversion efficiency of the motor, and the engine needs to increase the rotational speed for providing the required charging torque.

It is understood that the target load refers to a load in an on state at the present time, and the target load may include a vehicle high-voltage accessory and a vehicle low-voltage load. The number of the target loads can be multiple, the total rated power of each target load is calculated through the rated power of each target load, the low-voltage required power generation torque is determined according to the total rated power of the low-voltage load of the vehicle, the high-voltage required power generation torque is determined according to the total rated power of the high-voltage accessory of the vehicle and the conversion efficiency of the direct-current converter, and the low-voltage required power generation torque and the high-voltage required power generation torque are calculated to obtain the required power generation torque.

Further, the high-voltage accessory of the vehicle in the first target load may include a high-voltage battery cooling system, a high-voltage battery preheating system, a driving motor cooling system, etc., and the low-voltage accessory of the vehicle in the first target load may include a combination meter, an anti-lock system, etc. And calculating the total rated power of each first target load through the rated power of each first target load, and further determining the minimum required power generation torque according to the total rated power of the first target load.

In one possible implementation, calculating the vehicle-by-vehicle generation torque includes a loss power of the wiring harness during operation of the target load. Namely, the whole vehicle power generation torque= (wire harness loss power + rated power of each target load)/whole vehicle conversion efficiency/(engine speed unit conversion factor).

The method comprises the steps of responding to a command for charging a high-voltage battery of a hybrid electric vehicle, calculating a required charging torque meeting the charging requirement of the high-voltage battery and a required power generation torque meeting the target load work of the hybrid electric vehicle to obtain the whole vehicle power generation torque of an engine, wherein the whole vehicle power generation torque is the sum of the required charging torque and the required power generation torque, calculating the minimum required power generation torque meeting the first target load work related to vehicle running and safety in the target load, and controlling the power generation output torque of the engine to be increased to the whole vehicle power generation torque according to the required charging torque, the required power generation torque and the minimum required power generation torque. In this way, in the process of controlling the power generation output torque of the engine to increase, the power generation output torque of the engine is controlled to increase to the power generation torque of the whole vehicle by the minimum required power generation torque, so that the risk that the engine is easy to stall when the hybrid power vehicle starts to charge the high-voltage battery is reduced on the basis of ensuring the power performance of the vehicle, and the running stability of the vehicle when the vehicle starts to charge the high-voltage battery is improved.

Alternatively, referring to a flowchart for implementing step S13 in fig. 1 shown in fig. 3, the controlling the output torque of the engine to increase to the whole vehicle generation torque according to the required charging torque, the required generation torque, and the minimum required generation torque includes the following steps.

In step S131, the demand and torque of the minimum required generation torque and the required charging torque are calculated, and a second one of the target loads, which is independent of the running and safety of the vehicle, is turned off.

In step S132, the engine is controlled to increase the power generation output torque with the demand and torque as targets.

In step S133, in the case where the power generation output torque of the engine increases to the demand and torque, the high-voltage battery is charged, and a timer is started.

In step S134, if the timing duration reaches the calibration duration, the engine is controlled to increase the power generation output torque with the power generation torque of the whole vehicle as a target.

In step S135, in the case where the power generation output torque of the engine increases to the whole vehicle power generation torque, the second target load is turned on.

Alternatively, the second target load may include a seat heating device, an air conditioner heating device PTC, an air conditioner cooling EAC, a multimedia music device, a steering wheel heating device. Optionally, the response time of the actual engine to the charging instruction is between a few seconds, and during the response time of the engine, the closing of the load related to the driving and the safety does not affect the driving and the safety of the vehicle, so that the load of the part can be calibrated to belong to the second target load, for example, the heating of the rearview mirror is closed during the response time of the engine, the driving and the safety of the vehicle are not affected, and the heating device of the rearview mirror can be calibrated to belong to the second target load.

Specifically, the second target load is closed, the load which is not closed in the target loads is the first target load, and the power consumed by the first target load during operation is the power corresponding to the minimum required power generation torque. The whole vehicle controller further aims at the requirements and the torque, improves the rotating speed of the engine, ensures that the driving torque of the engine for driving the vehicle to run is unchanged, and controls the engine to increase the power generation output torque.

Further, the whole vehicle controller determines that the rotation speed of the engine corresponds to the provided whole vehicle power generation torque to meet the requirements and the torque under the condition that the driving torque is unchanged, charges the high-voltage battery, and controls a timer in the whole vehicle controller to start for timing.

Further, if the timing duration reaches the calibration duration, stopping timing, and controlling the engine to increase the power generation output torque by taking the power generation torque of the whole vehicle as a target, so as to realize the increase of the power generation output torque (the power generation torque of the whole vehicle) of the engine based on the minimum required power generation torque gradient.

By adopting the technical scheme, in the process of controlling the increase of the power generation output torque of the engine, the second target load is closed, the increase of the power generation output torque of the engine is reduced, the power generation output torque of the engine is improved by the requirement and the torque of the minimum required power generation torque and the required charging torque, and then the power generation output torque of the engine is improved by the difference value between the power generation torque of the whole vehicle and the requirement and the torque. The power generation output torque of the engine is increased in a gradient manner, so that the high-voltage battery can be charged under the condition that the driving torque of the whole vehicle is unchanged, and abnormal flameout of the engine due to insufficient output torque is avoided when the high-voltage battery starts to be charged.

It can be stated that the calibration time is to make the rotation speed of the engine reach relatively stable, i.e. the power generation output torque of the engine is relatively stable, and the rotation speed of the engine is dynamically changed in real time, and after the power generation output torque of the engine is not balanced, the power generation output torque of the whole vehicle is controlled to be used as a target to increase the power generation output torque. Thus, the power generation output torque of the engine is controlled to be increased in gradient by the calibrated duration.

It can be stated that if the difference between the power generation torque of the whole vehicle and the minimum required power generation torque is smaller than or equal to the preset threshold value, the power generation output torque increase value of the engine is smaller, and in this case, the possibility that the engine is flameout due to abnormal negative torque of the power generator is smaller, and the power generation output torque of the engine can be directly increased to the power generation torque of the whole vehicle. Therefore, when the difference between the power generation torque of the whole vehicle and the minimum required power generation torque is larger than the preset threshold value, the step S13 is executed, so that the risk of abnormal flameout of the engine due to insufficient output torque when the high-voltage battery starts to be charged can be effectively reduced, and the rationality of the power generation output torque of the engine is improved.

Optionally, the method further comprises:

Specifically, when the high-voltage battery is stopped, also because the response speed of the engine is slower than the response speed of the motor, when the instruction to charge the high-voltage battery is received, t3 of the motor in response to the instruction to stop charging is shorter than the response time t4 of the engine in response to the instruction to stop charging. During the response time t4 of the engine, the rotation speed of the engine is continuously reduced, and during the process of reducing the rotation speed of the engine, the torque output by the engine to the motor for generating electricity is excessive, so that the motor is damaged.

Therefore, the whole vehicle controller determines the target output torque of the engine for generating electricity through the torque gradient table according to the current opening and closing degree of the accelerator pedal, the current vehicle speed, the current temperature of the cooling liquid of the engine, the current charge state of the high-voltage battery and the current running time of the engine, further determines the speed reduction speed of the engine, can effectively reduce the torque of the engine, which is output to the motor for generating electricity, in the process of reducing the engine speed, and reduces the risk of damage of the motor.

In one embodiment, referring to fig. 4, when the driving motor starts driving the vehicle based on the power supplied from the high-voltage battery, that is, the sum of the driving torque supplied from the driving motor and the driving torque supplied from the engine is used for the driving. The response time t5 of the driving motor in response to the driving instruction is shorter than the response time t6 of the engine in response to the driving instruction. In the response time t6 of the engine, the rotation speed of the engine is continuously reduced, and in the process of reducing the rotation speed of the engine, the driving torque output by the engine to the whole vehicle for driving is excessive, so that the risk of sudden acceleration of the vehicle exists.

In one implementation, the driving torque of the engine can be distributed to the power generation output torque by turning on the consuming load, so that the driving torque can be reduced, and the risk of sudden acceleration of the vehicle can be effectively reduced.

The following describes a control method of engine output torque of a hybrid vehicle with a control logic diagram of the vehicle controller according to an embodiment, and referring to fig. 5, the method includes:

the whole vehicle controller calculates the wire harness loss power in the first target load working state, calculates the sum of the direct current converter power and the wire harness loss power, and further determines the minimum required power generation torque according to the whole vehicle conversion efficiency and the engine rotating speed.

Further, the required power generation torque is calculated by calculating the rated power of the target load in the on state, the difference between the required power generation torque and the minimum required power generation torque is calculated, the difference is the required power generation torque corresponding to the power consumed by the second target load in operation, the required charging torque corresponding to the charge state of the high-voltage battery is calculated, and the required and torque are calculated according to the minimum required power generation torque and the required charging torque.

Further, the whole vehicle controller calculates the whole vehicle power generation torque according to the required charging torque and the required power generation torque, and it can be understood that the electric power provided by the motor passes through the Filter to obtain the actual electric power.

And under the condition that the timing duration reaches the calibration duration, controlling the engine to increase the power generation output torque or controlling the engine to increase the output torque by taking the difference as a target, so as to realize the power generation control of the whole vehicle.
